How to Use P, R, N, D, and S Gears?
1 Answers
P is the parking gear, R is the reverse gear, N is the neutral gear, D is the drive gear, and S is the sport mode. P gear: Used when parking and turning off the engine; N gear: Used for short stops without turning off the engine; D gear: Used for driving forward; R gear: Used for reversing; S gear: Used for aggressive driving or overtaking. More detailed explanations are as follows: 1. Automatic transmission cars have the above-mentioned gears. There are three common types of automatic transmissions in cars: AT transmission, dual-clutch transmission, and CVT transmission. 2. The dual-clutch transmission is a product developed based on the manual transmission. The structure of this transmission is similar to that of a manual transmission. The dual-clutch transmission simply has an additional set of clutches and a shift control mechanism compared to a manual transmission. One set of clutches in this transmission controls the odd-numbered gears, while the other set controls the even-numbered gears. 3. The dual-clutch transmission has fast shifting speed and relatively high transmission efficiency. There are two types of dual-clutch transmissions: dry-type and wet-type. 4. The clutch plates of the dry-type dual-clutch transmission are not immersed in transmission oil, while those of the wet-type dual-clutch transmission are immersed in transmission oil. 5. The wet-type dual-clutch transmission has better reliability and stability, and this transmission can also withstand greater torque. However, the wet-type dual-clutch transmission has a more complex structure and higher cost.
